风云卫星大气运动观测产品

大气运动导风（Atmosphere Motion Vectors）（也称“云导风”、“云迹风”、“大气运动矢量”），是使用气象卫星图像反演出的风场产品。该产品使用连续气象卫星图像追踪图像上示踪图像块的位移，并计算示踪图像块所代表的云或水汽等特征所在的高度层次，从而获得这些层次上风的大小和方向。

Atmospheric Motion Vectors (also known as "cloud-derived wind", "cloud-track wind", and "atmospheric motion vectors") are wind field products retrieved from meteorological satellite imagery. This product tracks the displacement of tracer image patches across consecutive meteorological satellite images, estimates the altitude layers where the features (e.g., clouds or water vapor) represented by these tracer patches reside, and thereby derives the magnitude and direction of winds at these layers.
